Let's face it, we all did stupid things at sleepovers back in the day.

From mooning out our BFF's front door to knick-knocking on neighbour's houses, our common sense went straight out the window the minute we saw each other in jammies.

So, we can totally relate to one 15-year-old girl from the States who actually managed to get her head stuck in a giant Barney the Dinosaur costume during a recent slumber party.

Proving that the excitement had clearly gotten too much for her, Darby Risner stuck her noggin inside a discarded Barney head and promptly got stuck.

After enlisting the help of emergency services who got to work with a lot of Vaseline and some intricate scissor work, the Alabama teen was finally freed, but not before her predicament hit social media sites. (Obvs.)

And unlike our Irish mammies who would have scared the bejaysus out of us with threats warning us not to be so stupid again, Darby's mam lolled as much as the teen's mates, laughing: "It gave her short little Barney arms since it was nearly at her elbows. It was hilarious."

Darby, you're a hero.
